Twine is a kind of light rope created by weaving together several small strings of thread. This thin cord-like material is often used for hay bailing or gardening. Twine's strength allows you to use it for countless other projects both outdoors and indoors in any setting. Though tying twine requires a little special consideration, the technique ultimately remains the same as tying any other kind of rope.
Stretch the twine slightly to ensure it will not snap. Do not strain too hard to stretch the twine, but stretch it until it presents a solid resistance. Once it shows resistance, stop stretching it to avoid weakening the twine.
Cross the two ends of the twine around each other, and pull them tight. Give yourself enough slack to further this knot. If you have excess twine on the ends of the knot, you can always cut them off.
Bring the two ends of the twine into a loop above where they cross. Make the loop large enough for your pinkie finger to fit through but not small enough to where the twine cannot fit through.
Cross the two ends of the twine through the loop, and pull them tight to create a knot where the loop meets the first cross. Twine will tighten considerably because of how the threads bunch up, so the knot will hold a lot of weight and become extremely difficult to untie. Usually, if you want to break the knot, you must cut the rope entirely.
